6 MooX::Types::MooseLike::Base - A set of basic Moose-like types for Moo
7
9 package MyPackage;
10 use Moo;
11 use MooX::Types::MooseLike::Base qw(:all);
12
13 has "beers_by_day_of_week" => (
14 isa => HashRef
15 );
16
17 has "current_BAC" => (
18 isa => Num
19 );
20
21 # Also supporting is_$type. For example, is_Int() can be used as follows
22 has 'legal_age' => (
23 is => 'ro',
24 isa => sub { die "$_[0] is not of legal age"
25 unless (is_Int($_[0]) && $_[0] > 17) },
26 );
27
29 Moo attributes (like Moose) have an 'isa' property. This module
30 provides some basic types for this property. One can import all types
31 with ':all' tag or import a list of types like:
32
33 use MooX::Types::MooseLike::Base qw/HashRef ArrayRef/;
34
35 so one could then declare some attributes like:
36
37 has 'contact' => (
38 is => 'ro',
39 isa => HashRef,
40 );
41 has 'guest_list' => (
42 is => 'ro',
43 isa => ArrayRef[HashRef],
44 );
45
46 These types provide a check that the contact attribute is a "hash"
47 reference, and that the guest_list is an "array of hash" references.
48
50 Any
51 Any type (test is always true)
52
53 Item
54 Synonymous with Any type
55
56 Undef
57 A type that is not defined
58
59 Defined
60 A type that is defined
61
62 Bool
63 A boolean 1|0 type
64
65 Value
66 A non-reference type
67
68 Ref
69 A reference type
70
71 Str
72 A non-reference type where a reference to it is a SCALAR
73
74 Num
75 A number type
76
77 Int
78 An integer type
79
80 ArrayRef
81 An ArrayRef (ARRAY) type
82
83 HashRef
84 A HashRef (HASH) type
85
86 CodeRef
87 A CodeRef (CODE) type
88
89 RegexpRef
90 A regular expression reference type
91
92 GlobRef
93 A glob reference type
94
95 FileHandle
96 A type that is either a builtin perl filehandle or an IO::Handle object
97
98 Object
99 A type that is an object (think blessed)
100
102 Parameterizing Types With a Single Type
103 The following types can be parameterized with other types.
104
105 ArrayRef
106
107 For example, ArrayRef[HashRef]
108
109 HashRef
110
111 ScalarRef
112
113 Maybe
114
115 For example, Maybe[Int] would be an integer or undef
116
117 Parameterizing Types With Multiple Types
118 AnyOf
119
120 Check if the attribute is any of the listed types (think union). Takes
121 a list of types as the argument, for example:
122
123 isa => AnyOf[Int, ArrayRef[Int], HashRef[Int]]
124
125 Note: AnyOf is passed an ArrayRef[CodeRef]
126
127 AllOf
128
129 Check if the attribute is all of the listed types (think intersection).
130 Takes a list of types as the argument. For example:
131
132 isa => AllOf[
133 InstanceOf['Human'],
134 ConsumerOf['Air'],
135 HasMethods['breath', 'dance']
136 ],
137
138 Parameterizing Types With (Multiple) Strings
139 In addition, we have some parameterized types that take string
140 arguments.
141
142 InstanceOf
143
144 Check if the attribute is an object instance of one or more classes.
145 Uses "blessed" and "isa" to do so. Takes a list of class names as the
146 argument. For example:
147
148 isa => InstanceOf['MyClass','MyOtherClass']
149
150 Note: InstanceOf is passed an ArrayRef[Str]
151
152 ConsumerOf
153
154 Check if the attribute is blessed and consumes one or more roles. Uses
155 "blessed" and "does" to do so. Takes a list of role names as the
156 arguments. For example:
157
158 isa => ConsumerOf['My::Role', 'My::AnotherRole']
159
160 HasMethods
161
162 Check if the attribute is blessed and has one or more methods. Uses
163 "blessed" and "can" to do so. Takes a list of method names as the
164 arguments. For example:
165
166 isa => HasMethods[qw/postulate contemplate liberate/]
167
168 Enum
169
170 Check if the attribute is one of the enumerated strings. Takes a list
171 of possible string values. For example:
172
173 isa => Enum['rock', 'spock', 'paper', 'lizard', 'scissors']
174
176 MooX::Types::MooseLike::Numeric - an example of building subtypes.
177
178 MooX::Types::SetObject - an example of building parameterized types.
